Modeling a 3D Eddy Current Problem Using the Weak Formulation of the Convective A-phi Steady State Method

J. Bird[1]

[1]University of North Carolina, Charlotte, North Carolina, USA

A 3D model of a magnetic rotor both rotating and translationally moving at high-speed over a conductive guideway is modeled in steady-state using the convective A*-Φ formulation. The presence of the magnetic rotor (source field) is incorporated into the formulation via the boundary ... Read More

A Multiphysics Approach to Fundamental Conjugate Drying by Forced Convection

M. de Bonis, and G. Ruocco
DITEC, Universitµa degli studi della Basilicata, Campus Macchia Romana, Potenza, Italy

Heat and mass transfer involved in drying is studied by using COMSOL 3.4. The effect of air temperature on the performance of the drying process applied to fresh food slices is scrutinized. COMSOL’s flexible formulation is exploited by using special drying kinetics for the substrate, ... Read More

Collection efficiency of particles on a ribbon in a turbulent air flow

R. Divigalpitiya[1]
[1]3M Canada Company, London, Ontario, Canada

The collection efficiency of aerosol particles on a ribbon in a turbulent flow is analyzed using COMSOL Multiphysics. The flow field is solved using Chemical Engineering module and particle tracing plots are obtained using equations of motion including Khan and Richardson drag force. A ... Read More

[1] Klipsch Group, Inc., Indianapolis, IN, USA

COMSOL Multiphysics® simulation software is receiving a lot of attention in the loudspeaker industry thanks to the quality of the results it provides making it an essential tool to optimize geometries so that the best reproduction capabilities of the loudspeaker system are achieved. ... Read More

Modeling Internal Erosion Processes in Soil Pipes

J. L. Nieber [1], G. V. Wilson [2], G. A. Fox [3],
[1] University of Minnesota, St. Paul, MN, USA
[2] United States Department of Agriculture - Agricultural Research Service National Sedimentation Laboratory, Oxford, MS, USA
[3] North Carolina State University, Raleigh, NC, USA

The erosion of the interior of soil pipes is an important process in the fields of geomechanics and geomorphology. Soil pipes can form in water holding structures like dams and levees, and water flow through these structures becomes concentrated into the soil pipes as they evolve by the ... Read More

Acoustic Upside-Down Levitator with a Solid Sample

L. Holitzner [1], E. G. Lierke [2],
[1] Paul Scherrer Institut (PSI), Villigen PSI, Switzerland
[2] tec5 AG, Oberursel, Germany

Introduction: Acoustic levitators are used to levitate small samples (ca. 0.01 - 6 mm) at a stable position in a gas or liquid environment. Acoustic levitators were first developed und used for experiments in space (1970s, by NASA / ESA), the application later became terrestrial (1990s). ... Read More

Surface Acoustic Wave Based MEMS Resonator

S. Dixit[1], R. C. Jain[1]
[1]Jaypee Institute of Information Technology, Noida, Uttar Pradesh, India

Surface Acoustic Waves (SAW) is the acoustic wave that propagates along the surface of the substrate with amplitude decaying exponentially away from the surface. A basic SAW device consists of two IDT’s on a piezoelectric substrate such as quartz. Surface Acoustic Wave can be ... Read More
